MySQL使用实例

https://learnsql.cn

误删除了vps上的phpmyadmin，不得已翻阅了半天mysql指南，以下是一些mysql使用实例

连接管理

链接数据库

mysql -h localhost -u root -p

退出数据库

mysql>quit;

数据库管理

查看数据库

mysql>show databases;

建立数据库

mysql>create database name;

备份(导出)数据库

mysqldump -u username -p database > backup_db.sql

还原(导入)数据库

mysql -u username -p database < backup_db.sql

用户管理

添加用户

mysql>grant all privileges on databasename.* 'username'@'localhost' identified by 'userpassword' with grant optiton;

删除用户

mysql>drop user username;

修改密码

mysql>set password for 'username'@'localhost' = password('userpassword');

一个创建数据库并添加专用用户的示例:

mysql> create database wp;
Query OK, 1 row affected (0.01 sec)

mysql> show databases;
+--------------------+
| Database         |
+--------------------+
| information_schema |
| mysql              |
| wp                 |
+--------------------+
3 rows in set (0.00 sec)

mysql> use up
ERROR 1049 (42000): Unknown database 'up'
mysql> use wp;
Database changed
mysql> show tables;
Empty set (0.00 sec)

mysql> grant select,insert,update,delete,create,drop
    -> on wordpress.*
    -> to 'wordpress'@'localhost'
    -> identified by 'passwd';
Query OK, 0 rows affected (0.03 sec)
